Abstract
Objective: To assess a drug delivery system that can rapidly achieve and maintain a constant blood concentration of Propofol (2, 6 di-isopropyl phenol) which, in subanaesthetic doses, is an effective intravenous sedative for treating anxious or handicapped patients in dentistry.
Design: The clinical use of a computer controlled infusion system to induce and maintain conscious sedation with propofol was prospectively studied. Based on a 3-compartment pharmacokinetic model, the system calculates the initial bolus dose and infusion rates to achieve a user-selected target blood concentration.
Setting: Amsterdam Center for Special Dental Care.
Subjects: 89 patients attending for dental treatment.
Results: Treatment could be performed within 2 minutes after the onset of the infusion. The median therapeutic target blood propofol concentration was 2.5 micrograms/ml and the median recovery time was 9 minutes. Transient oversedation (38 procedures) could easily be treated by decreasing the target concentration. No adverse cardiorespiratory effects resulted from propofol sedation. Venous blood propofol concentrations were measured in 25 anxious patients. The kinetic data set used in this study underestimated the distribution and elimination of propofol in our patients.
Conclusions: Computer controlled infusion of propofol can provide satisfactory and safe conscious sedation in dental patients
